Vintage Grundig rebuild

Turntable removed and the hole has been boarded up with a shelf that will hold the cable box and the blu-ray player. An IR repeater will be added to control those devices. The amp compartment will need to be opened to turn the amp on. No remote.

I have applied a coat of finish to the piece now. 2 more to go. Then I will re-gold the leg tips.

I am having a black plex faceplate made to surround the amp. It should look fairly stock when finished because the original amp had a black glass face.

My point was that the low frequency content on +R will equal +L 90% of the time and the drop across the woofer voice coil will be zero. But heck, what do I know? Maybe it will work just fine. That configuration is what Dynaco did back in the day for ambient recovery albeit with a full range signal. I would think a dual voice coil driver would be better but those are probably more likely in a subwoofer driver.

Edit: Or run the woofer from a single channel - and set the mono switch on the receiver.

Im trying not to buy any speakers. If it sounds bad, then I can replace the speakers. But remember, this is to function at the level of a soundbar. It is not hi-fi.
Here is the receiver fitted. Wiring it up (sans parts) this weekend in anticipation of the parts arriving next week.

I got to a place this morning after I had soldered all the wires in place that I could not resist any longer. I just hooked up the two speakers to the main outputs and the woofer to the left side of the remote output.

I turned the volume all the way down and then used the tuning meter to tune in a station. I raised the volume slowly and....there was music.
I pressed the mono button, and of course the loudness button and it still sounded pretty good for what I want to use it for.

So....when I get the proper parts in place (Monday) it should be ready to go. Hopefully getting the unwanted frequencies out of the various speakers will just make it sound better. Next, I need to remove the soundbar I use now from the wall and lower the television about 8 inches
. That is a full mornings worth of work. And I still need to put the other components into the Grundig and wire them all together.

I had a brain fart. I noticed my Blu-ray player didn't have an analog audio output so I went out in search of one that does. Of course the only option was a 700 dollar Oppo. Not gonna happen for this use.
Then, it struck me...all I needed was a cheap DAC. Off to Best Buy and 35 dollars later I can use my current blu-ray player with the vintage amp.
Sometimes you forget that you know stuff.
I also picked up an 1/8 jack to RCA patch cord so I can play music off my phone or an MP3 player as well.
After all is said and done, this could be sold for 6 or 700 bucks with the gear in it and I would still make a tidy profit. Too bad i'm keeping it.

Crossover parts installed, with a few surprises.
First to the end game...it sounds better than I could have ever imagined. Removing the low end from those two speakers really made a world of difference. Fantastic.

But, after adding the coil and doing the + to both sides of the woofer I had no bass. So I just went back to driving the woofer off one side of the remote speaker output, with the coil in-line. That did it up great! And removing the high end from the woofer really tightened the bass up too.

I could actually listen to this as a music source. There is no imaging or PRAT or any of that other stuff, but when I am just cleaning the kitchen or loungin on the sofa and want som music, this thing sounds really nice.
